What are the key features of SN74S140DG4?
- Dual 4-input NAND gate configuration provides two independent logic functions in a single 14-pin SOIC package
- High output sink current of 60 mA at VOL = 0.5 V enables direct line driving without external buffer stages
- Schottky (S) family technology delivers fast propagation delays for high-speed digital logic applications
- Green/RoHS-compliant plastic SOIC-14 package (MS-012AB) suitable for environmentally conscious designs
What is SN74S140DG4 used for?
The SN74S140DG4 is used in high-speed digital logic systems where dual 4-input NAND gating with strong drive capability is required, such as bus drivers, clock distribution, and address decode circuitry. Its high sink current makes it suitable for driving LEDs, transmission lines, and other medium-load outputs directly. The standard SOIC-14 footprint ensures compatibility with legacy board designs and automated assembly processes.
